A Bay Area high school teacher was put on paid administrative leave this week after comparing President-elect Donald Trump to Adolf Hitler.

Frank Navarro, a history and special education teacher at Mountain View High School, was asked to leave during school hours on Thursday after the administration received an email from a parent concerned about statements he made in class, the Mercury News reported.

Navarro, who has taught at the school for 40 years, told the Mercury News that his lesson plan was based on historical fact and that Hitler’s persecution of Jews and rise to power has “remarkable parallels” to the president-elect’s statements about Latinos, Muslims and African Americans during his bid for the presidency.

He said he told school officials: “I’m not pulling these facts out of my hat. It’s based on experience and work, and if I’m wrong, show me where I’m wrong. And then there was silence,” the Mercury News reported.
